Field flattener / Focal Reducer for WO Zenithstar 80

[tdmodels]

Does anyone have an opinion or guidance on a suitable FF/FR for my WO Zentihstar 80?  I have heard various reports (good and bad) regarding the WO version 3.  Also not sure whether the version 4 is suitable for this scope.

Any pointers would be gratefully received.

Cheers,

Tim

This is the one I use with my ZS80FD:

It is able to deliver a flat field over my QHY8L.

Hi Tim i borrowed my firends ED80 and he has the WO FF/FR on it and to be honest it doesnt do much but its a not matched for sw ed80 so i couldnt really give you an answer on how it preforms on a WO scope but as you've said it does have some rubbish reviews. you could always just get a FF http://www.firstlightoptics.com/reducersflatteners/hotech-sca-field-flattener.html good price or depending on budget  http://www.green-witch.com/acatalog/Adapters_TeleVue.html  the TV TRF2008 is 2nd from bottom this had excellent reviews. i have a wanted advert out for one at the moment but there hard to come by 2nd hand as there really good. my Equinox is F6.3 and it would make it and F5 with this, HTH
